IMPROVE BRICK-MACHINE.-

The Schedule referred to in these Letters Patent and making part cf the same.

"clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying draw ings, forming part of this specification.

This invention relates .to a new and improved machine for making bricks, and has for its object simplicity and economy in construction, rapidity of execution, and vpressure-power requisite to form perfect bricks from Well-tempered clay.

-In the accompanying sheet of drawings- Figure l is a vertical section of myinventiou, taken in the line :t a, iig. 2. Y l

Figure 2,- a horizontal section of the same, taken in the line y y, iig. 1.

Similar' letters of reference indicate corresponding parts.

A represents the box or case of the mud-mill of the machine.

This box or case is fitted on a suitable base, B, and has lwithin it a vertical shaft, C, on the top of which a sweep, D, is secured.

The shaft C has a series of arms or blades, a, projecting from it horizontally, and in' a spiral line from its upper 'to its lower part, (see iig. 1,) while on the lower end of the shaft there are secured spirall or screw-blades,-A*, (three, more or less,) which serve to press the clay through an opening, b, into the. mould underneath.

The clay, properly moistened, is placed, as usual, into box or case A, and the shaft O being rotated by horse or other power, the arms or blades a' temper the clay, and at the same time, owing to their spiral attachment to theshait, feed the clay down to the bottom of the box or case..

Oli the upper part of the shaft C there is keyed a spur-wheel, E, which gears into a pinion or smaller wheel, F, on a vertical shaft,.G, at tbe outer, side of the box or case A, the relative'diametel'of the wheel E and pinion F being such that thesbaft G will make two and a half (2%) revolutions to one-of shaft O.

On the lower end of the shaft G there is keyed a crank, H, the pin c of which works in an oblongr slot in a horizontal slide, I, underneath the mud-mill.

This crank-wheel gives a reciprocating movement to the slide I, and the slide moves the moulds, one ata time, underneath a pressure-roller, J, placed at the lower part of'v one side of the case or box A, and also underneath a scraper, K, at the outer side of roller J. The empty moulds are fed into the-machine at one side ofthe same, and in front of the slide I, bymeans of a sliding plate, L, which works in a groove, d, in a platform, M, attached to the vbase of the' machine.

This platev L is connected to a lever, N, -by means of a Vpiu passing throughan oblong slot, e, in thelever, and said lever is of bent form,'haviug its fulcrurn at j,

v'(see iig. 2,) and its short arm g is actuated from the slide I, the long arm h being'connected with plate L.

The short arm g is acted upon' by an ar1n, 'i, attached to slide I, the latter, as it moves inthe direction indicated by the arrow 1, causing the plate L to, move in the direction indicated by arrow-2, and feeding the `brick-mould under the case or box A, lso that it can be iilled with clay, and also placingit in front. of slide I, the latter, as it returns in the direction indicated by arrow 3, forcing the filled mould under-roller" J, which is rotated at this time by a pawl, j, engaging r with a ratchet, It, attached to one end of the roller, the

pawl being pivoted to a lever, l, which is operated from the slide I, in consequence of being connected therewith bya rod, m, as shown clearly in fig. 1..,

The roller compresses the clay inV the mould, and the scraper K removes the superfluous clay therefrom.

At the termination of the forward movement of the slide I, there is a dwell or cessation of movement sufciently long to admit of an empty mould being placed or adjusted in front of plate L, ready to be shoved into the machine as the slide approaches the termination of its backua'rdmovement.

Whenl the slide I moves forward and feeds-a filled mould to the 'roller J, a spring, a, actuates the bent lever N, andthrows the plate L back, to admit of an empty mould being placed in front of it.

Having thus described my invention,

WVhatI claim as new, and desire to secure by Letters Patent, is-

The brick-press, with the gearing E F, shaft Gr,

clank H, and slides I and L, constructed and arranged as described, and to operate in'combination with the roller J and scraper K, in the manner and for the purpose substantially as set forth.

The above specification of my invention signed by me, this 14th day of July, 1868.
